It says cylinder 3 misfire can i just fix the cylinder or do i need to get a new engine. Around 1,900 rpm my truck shakes like crazy. lol
i got a 04 f150 ext.cab FX4.

If i need a new engine is there a more powerful engine i can swap it with.

 

You probably just need a coil plug or an injector. Ever tune it up? I bet not.

 

What size motor?

 

How many miles on it?

 

5.4

132,000 miles

 

Take it to the dealer for a tune up. The breaking plug issue at that mileage and you are probably not equipped for it.

 

definitely an electrical problem not mechanical.
